/**
 * Bare-path diff helper for `qfg push`.
 *
 * When the user's local dir is NOT a clone of the cloud repo (no `.git/`, or
 * a mismatched origin) we still need to show a Guard 3 diff summary BEFORE
 * asking them to confirm the push. The clone-path implementation uses
 * `git log origin/main..HEAD` — that doesn't work here because there is no
 * origin in the local dir.
 *
 * Strategy: probe-clone the cloud repo into an OS tmpdir, then walk both
 * trees file-by-file and classify each as added / modified / deleted.
 *
 * The caller owns cleanup of `scratchDir`. The real caller (buildRealDeps in
 * `commands/push.ts`) stashes the scratch clone path on a closure so it can
 * delete it in a finally-block after runPush resolves — matching the bare
 * path's existing scratch-clone lifecycle in `run-push.ts`.
 *
 * Intentional non-goals:
 *   - No token handling. Caller passes a fully-authenticated `remoteUrl`.
 *   - No filtering to "known" workspace dirs (configs/, feature-flags/, ...).
 *     We exclude dotfiles/dotdirs (`.git`, `.DS_Store`, `.quonfig-*`) so the
 *     scratch clone's own `.git/` does not leak into the diff, but otherwise
 *     diff whatever is on disk. This keeps the diff surface consistent with
 *     `copyDirMirror` in `commands/push.ts`, which mirrors every non-dotfile
 *     into the real push clone.
